Contributions and role of B2 nanoparticles in the exceptional strength/ductility trade-offs of Al0.3CoCrFeMnNi high entropy alloy

Materials Research Letters
This study explores the role of B2 nanoprecipitates in enhancing strength/ductility trade-offs in the Al0.3CoCrFeMnNi high-entropy alloy (HEA). A tailored thermomechanical treatment selectively introduced high-density intragranular B2 nanoprecipitates ...

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Benchmarks for Accelerated Cyclic Plasticity Models with Finite Elements

Metals, 2020
In numerical simulations of components subjected to low-cycle fatigue loading, the material cyclic plasticity behavior must be modelled until complete stabilization, which occurs approximately at half the number of cycles to failure.

Stress-strain response and microstructural evolution of a FeMnCAl TWIP steel during tension-compression tests [PDF]

, 2016
© 2016. The stress-strain response of a Fe-17.5Mn-0.7C-2Al TWIP steel during cyclic loading has been investigated by means of tension-compression tests within the strain limits of ±2%, ±5% and ±10%. In addition, the microstructural evolution during the ±
